That worryingly wide grin just grows even wider. If Tyki can fell a tree or a boulder then hell yes, Strange wants to test and see if he can store it in a reflection! This is a brilliant plan!

"The lake would be our best choice," Strange explains, as he gestures towards the lake. "I'll prepare the spell and prime the magic. We push the boulder into the lake, it stays trapped in the reflection for however long we want, and then when the spell's lasted long enough, I release it and it sinks to the bottom!"

It's a solid plan in Strange's mind. He obviously has no qualms changing the topography of this place and messing up the natural environment of camping world. After all, a lot of his time in the peninsula was spent trying to move forests and rivers and occasionally forgetting to put things back. He looks like he's ready to get up and do it, despite the fact that it's night outside and they probably shouldn't be felling trees in the dark.

"What do you think?"
